MACHINE FOR BORING HOLES IN BUTTONQ SPECIFICATION forming part of Letters Patent No. 639,909, dated Deceinkeri 26, 1899.

Application filed Jul 20, 1896.

T0 (tZZ whom it may concern:

Be it known that I, DILMAN BRUBACHER SHANTZ, manufacturer, of the town of Berlin, in the county of Waterloo, in the Province of Ontario, Canada, have invented certain new and useful Improvements in Machines for Boring Holes in Buttons, of which the following is a specification.

My invention relates to improvements in machines for boring holes in buttons and similar articles patented to me in Canada on the 3d day of October, 1892, and in the United States on the 26th day of December, 1893, under No. 511,864; and the object of my pres ent invention is to provide a convenient automatic means of feeding the buttons into position between the stationaryand movable chuck in which they are held for boring, and. thereby efiect the saving of time and labor and at the same time prevent the frequent spoiling of the button incident to its being fed by hand into position between the chucks; andit consists, essentially, of a chute the lower end of which is provided with a downwardly-extending holding-plate designed to coact with the upper extension of the stationary holding-chuck, peculiarly-operated arms beingprovided,whichare also designed to grip and lower the button into position between the stationary and movable chuck, and, further, in providing at the upper end of the chute a feed-hopper in which the buttons are placed, which hopper is provided with rotating arms designed to facilitate the feedand placing of the buttons from the hopper into their proper position in the chute and wise constructed to coact with the above mechanism in the manner hereinafter more particularly explained.

Figure l is a perspective view of a portion of my machine for boring holes in buttons, showing the attachment for the automatic feed of the buttons. Fig. 2 is asectional perspective view. Fig. 3 is a sectional detail of the top of the chute, showing the form of the adjustable selectin g-plate to secure the proper deposit of the button from the hopper into the chute. Fig. 4 is a perspective detail showing the means for adjusting the sides of the chute. Fig. 5 is a perspective detail of the front disk of the hopper and the arc-shaped guiding- Serial No. 599,943. (No model-T are the standards, on which are supported the inner ends of the drill-spindles;

C is a bracket having attached thereto an adjustable supplemental bracket 0', through which the free ends of the drill-spindles D pass.

E is the standard,at the top of which is supported the adjustable drill-holder F, through a which pass the outer ends of the drills G.

H is an arbor which has secured at one end the worm-wheel I, which meshes with the worm J on the main driving-shaft K of the machine. On thearbor H is secured the cams L and M, which regulate the movement of the lever Q, the gripping-fingers for the blank, and the backward-and-forward movement of the carriage P. The carriage P is supported on the base-plate between suitable guideways and given a backward-andforward movement in the same manner as in my former patents above referred to. lever Q is pivoted near the bottom at g on the forward end of the carriage P. r v

R is a chuck secured in the ring-shaped top of the lever Q.

q is a spiral spring which extends into a recess'in the carriage P and is designed to press upon the lever Q.

S is a lever pivoted at s in the lugs forming part of the bed-plate A. The lever S of course extends through the bed-plate and is provided at the lower end with a roller 8, journaled in jaws s which rolleris designed to have frictional contact with the cam L.

T is a rod which has a bent end t, which extends into the lever Q. The opposite end of the rod is threaded and is provided with an adjustable collar 25. The threaded end of the rod T extends freely through an opening 5 in the lever S.

U is a plate secured on the end of the forwardly-extending portion P of the carriage P. The plate U is reduced in size at its upper end and extends vertically upward into the The front side V of the hopper V. The plate U forms the. front side of the chute U.

The hopper V is provided at its exterior with a bracket V, which is securedto the Vertical rod W, which extends upwardly from and is secured to the carriage P. It will thus be seen that the hopper V is supported by means of the bracket \V and vertical rod W upon the carriage.

X is a spindle which extends through the hopper V, as shown, and is journaled at one end in the bracket W, in which it is held from moving longitudinally by means of the collar w. The opposite end of the spindle X extends through and is secured to the hub 11 of the disk V at the frontside of the hopper V and an arm V attached to or forming part of the bracket Y, which is suitably secured on the vertical spindles W W The spindle X is provided with a sprocket-wheelX,which is connected by a sprocket chain X to a sprocket-wheel X secured on the extension H of the arbor H. The extension H of the arbor H is connected by a toggle-joint. h to the arbor H and is journaled at its opposite end in an arm h, secured to the frame of the machine. (See Fig. 6.) By means of the cross sprocket-chain X it will be seen that the spindle X derives its rotation from the arbor H.

W is a vertical rod which is also secured at the bottom to the carriage P and also extends through the bracket Y, which it also serves to support. The bracket Y is provided with an outwardly-extending wingY, through which extend the set-screws y. The inner ends of the set-screws 11 are provided with annular grooves 'y,.into which extends the plate 1 which is secured by the screws y to the rear side U of the chute U. By

. means of the set-screws y the rear plate U may be adjusted in relation to thefront plate U in order to accommodate different thicknesses of buttons.

Y is a spring-plate having a forked lower end g, which extends into proximity with the plate U.

Y is a slot in the plate Y and Y is a setscrew which extends through the slot Y into the plate U such set-screw being designed to be loosened in order to adjust the height of the forks y.

The upper end of the bracket Y is formed with a level plate Y above the wing Y, such plate having a vertical inner end y, which is provided with a slot 3 the bottom of which is formed by the top of the plate.

1 is the outer upturned end of the plate Y Z is a plate which lies upon the plate Y and has a broad V-shaped notched inner end which extends into and forms a guide at one side of the chute U in order to insure the convex portion of the button coming down on the side in which the notch is formed and the;

down by the top of the slot 3 and is held from lateral movement by the plug y (See Figs. 1 and 3.) The plate Z is adjusted longitudinally by means of a set-screw z, which extends through the upturned end y" and has a reduced end provided with a knob, which reduced end extends through an eye z,attached to or forming part of the plate Z. By means of the set-screw z the plate Z may be adjusted in the chute to accommodate the difierent thicknesses of buttons.

The disk V, hereinbefore referred to, is provided with peripheral grooves a), which fit a tongue to at the top of the plate U.

2 is a ring connected by the arms 3 to the hub 4t, secured to the spindle X. The ring 2 is located on the outside of the front plate V of the hopper, said ring surrounding the edge of the opening V made in said plate. The arc-shaped guide 5, forming a part of the bracket 6, which is seen red to said front plate V abuts the outside edge of said ring. The

bracket 6 straddles the disk V and is provided at its outer end with an arc-shaped guide 7, which abuts the disk V.

8 is a finger which is located at the inner side of the disk and has a plate 9, which extends through a slot 10, made in the disk V. The plate 9 is attached to or forms part of the detent l0, pivoted at 11 on the outside of the disk V.

12 is a spring which is fastened at one end to the disk V and at the opposite end to the detent 10, the object of the spring 12 being to cause the detent to have an outward pressure against the arc-shaped guideway 7.

As the spindle X is caused to revolve it carries with it the ring 2 and disk V. The buttons. which are in the hopper are kept continually stirred up or,more properly,prevented from wedging or sticking by the arms 3. The buttons are carried down between the ring 2 and the disk V. If a button should not be carried down with the fiat face next the disk and the plate U and the convex face next the broad V-shaped notch in the plate Z, it will necessarily stick. In order to remove this button and allow of a a button which is properly placed in the top of the chute, to pass down to such chute, I provide, as hereinbefore described, the finger S, which as the disk V revolves is carried around with it and is forced outwardly at the bottom,when the detent 10 is relieved from contact with the arc-shaped guideway 7. This outwardlyextending movement of the finger 8 will carry the button away from the chute, as such finger will pass out to the periphery of the disk. As the finger 8 passes onwardly in its revolution and as the disk rotates in the direction indicated by arrow, such button will be carried upwardly circum ferentially until the finger is pressed inwardly through the detent 10, whereupon the arc-shaped guideway 5 will carry such buttonwithin the vortex of the circularly-moving disk, against which all the but- .tons are pressing, and such button I find in practice will turn eventually, as will all of the buttons, and pass down into'the chute with the face toward the disk and the convex portion toward the ring, so that such button may pass the broad V-shaped selecting-plate Z.

In order to further insure the improperlydeposited button from sticking above the selecting-plate, I provide an arm 13, which is pivoted at 14 on a plate 15 and is also pivotally connected to such plate by a pin 16, extending through a slot 17 in the arm 13. The arm 13 extends upwardly in the position shown in Fig. 2 into a slot u, madein the front side of the plate U of the chute U, such slot being a vertical one and preferably extending above and below the lever of the selecting-plate Z. The plate 15 is pivoted on the pin 16 and is connected by a pin 17 to a rod 18, the front end of which is preferably slightly curved, so as to extend around the head of the pin 16, so as to hold the plate 15 firmly on its seat and yet not prevent its swinging movement. The rod 18 extends through a hole in the top of the rod 19, secured in the top of a standard B.

20 are collars secured to the rod on each side of the standard by a set-screw, and 21 are spiral springs extending between the collars and the rod 19. The springs 21 are designed to relieve the pressure from the end of the arm 13.

Upon each forward movement of the carriage, bringing with it the hopper and bracket Y and the coacting mechanism, it will be seen that on account of the end of the rod 18 being pivotally connected to the plate 15, as hereinbefore described, such plate will be caused to swing upwardly toward the chute, carrying with it the arm 13, which will pass upwardly through the slot u and poke out any button which would have a tendency to stick against the selecting-plate Z.

It will be seen that the slot 17 in the arm 14 allows of the free upward movement of the inner end of the arm in the chute.

The means above described, it will be readily understood, effectually form an auxiliary means for relieving the upper end of the chute from an improperly-placed button.

The chute U is provided with sides U which have openings or perforations a so as to enable the operator of the machine to see the buttons as they pass down through the chute. In order to provide for the adjustment of the sides of the chute to accommodate and guide centrally the different diameter of buttons, I provide the following simple arrangement, which is clearly shown in Fig. 4:

22 are notches made in each side of the front plate U of the chute.

23 are plates which extend through the notches 22, such plates being secured to the sides U of the chute at the back of the plate U.

24 is the screw-spindle, which extends through the forwardly-extending portions of the plates 23, the spindles being secured from lateral movement by the pin 25, extending between the collars 26, secured to the spindle.

One end of the spindle has a right-hand thread and the other a left-hand thread. It will therefore be readily seen that by turning the knob of the screw-spindle the side plates U of the chute may be adjusted to or from each other, as desired.

In order to provide for the delivery of the button from the bottom of the chute to between the receiving-chucks opposite the boring-spindle, I provide the following mechanism:

27 is an arm which is secured to the carriage P and extends upwardly in the form shown.

28 is a table forming part of the lever 28, pivoted near the upper end, and 29 are curved gripping-fingers which are pivoted at 30 near the arm upon the top of the plate, so that they may have a lateral movement at the free end. The curved free ends of the arms 29 are preferably disk-shaped, as indicated.

31 is a spindle provided with a knob which extends through thefingers 29, being secured to one arm and extending freely through a hole in the other.

32 is a tension-spring which extends between the fingers 29 and through which the spindle 31 extends. The spring 32 is attached to both fingers, and the natural tendency of such spring is to draw the fingers together.

33 is an arm pivoted at the top of the arm 27, and 34 is a boss on such arm.

35 is a set-screw extending through the upper end of the arm and designed to be brought normally against the boss 34 by means of the spiral spring 36, connected to the top of the arm 27 and to the arm 33.

37 is a pin which extends laterally through each side of the arm at the lower end.

38 are disks secured to the inside of each arm, such disks having preferably substantially conical inner sides.

40 is a rod pivotally connected to the lever 28. The lever 40 hasa threaded end 40,which extends freely through the collar 41, secured 'The end of the rod 44 is threaded and is provided with an adjusting-nut 45, as shown.

The operation of the fingers 29 in delivering the button from the bottom of the chute between the chucks is as follows: The fingers 2 9 are shown in Figs. 1 and 2 in the position after they have gripped the button. After the button has reached the position shown in dotted lines against the bottom end of the spring-arm Y and is gripped as shown the cam L operates on the lever S, rod 44, and lever 28, so as to bring down the fingers 29,with the button in between the ends, past the forked spring-plate Y into position centrally between the chucks, the chuck R of which is now held open. Immediately this positionis reached the cam L will operate upon the rod T and lever Q and allow the spring q to close the chuck R and hold the button against the stationary plate U, which is provided with a hole through which the drills operate. At the same time the cam L will be pulling through the lever S and rod 44 upon the le- Ver 28, tilting it in the opposite direction,and carrying up with it the fingers 29, which when the conical disks 3b reach the laterally-extending pins 37 on the end of the arm 36 such fingers 29 will be forced apart momentarily, so as to pass freely the next deposited button above the forked end of the spring-plate Y After the pins 37 have passed the disks 38 the spring 32 draws the fingers together to grip the succeeding button held by the forked end 3 of the plate Y When the fingers 29 are again caused to move downwardly after the button is gripped, as hereinbefore described, it will be readily seen that the conical bosses 38 would slide past the pins 37, extending laterally out from each side of the arm, the spring 32 allowing of the giving of the arm 33 for such purpose.

It will thus be seen that I have provided in my attachment a means for gathering the buttons together successively in their proper relative position to enter the chute, in which they are held one above the other, and means for gripping each button as it passes down beyond the end of the chute and carrying it into position between the stationary and longitudinally-moving chuck. When held between such chucks, of course, the boring is done, and the finished button is deposited or carried off in any suitable manner.
